2008-09-1716550A UART: RHR irq enable bit also masks the Rx timeout irq.balrog
The "Rx timeout" (aka. Character Timeout Indication) has no separate mask bit in the IER register and according to the specs reading RHR is the only way to reset the irq. However on the hardware (tested on OMAP2 UART which is an extended 16550A) the RHR_IT bit in IER disables the irc, too. Linux bluetooth serial dongle driver for N800 depends on this behavior. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5239 c046a42c-6fe2-441c-8c8c-71466251a162

2008-09-16block-raw is not a protocolaliguori
The protocol_name "file" was added to the block driver when async IO was introduced. This can be used to select that a file is treated as a raw device instead of probing for the type. However, protocols are not subject to path interpretation which cases qcow2 images with raw base images to not function is the path was specified relatively. The fix is simply to remove the protocol_name from the raw block driver. The proper way to force the use of a raw block format is to use the format= option with -drive.

2008-09-15Make page_find() return 0 for too-large addresses (Eduardo Habkost)aliguori
On some cases, such as under KVM, tb_invalidate_phys_page_range() may be called for large addresses, when qemu is configured to more than 4GB of RAM. On these cases, qemu was crashing because it was using an index too large for l1_map[], that supports only 32-bit addresses when compiling without CONFIG_USER_ONLY.

2008-09-15Use common objects for qemu-img and qemu-nbdaliguori
Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the code. It's ugly and causes us to have to build multiple object files for linking against qemu and the tools. This patch introduces a new file, qemu-tool.c which contains enough for qemu-img, qemu-nbd, and QEMU to all share the same objects. This also required getting qemu-nbd to be a bit more Windows friendly. I also changed the Windows block-raw to use normal IO instead of overlapping IO since we don't actually do AIO yet on Windows. I changed the various #if 0's to #if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows. After this patch, there are no longer any #ifdef's related to qemu-img and qemu-nbd.

2008-09-14usb: Support for removing device by host addr, improved auto filter syntax ↵aliguori
(Max Krasnyansky) This patch adds support for removing USB devices by host address. Which is usefull for things like libvirtd because there is no easy way to find guest USB address of the host device. In other words you can now do: usb_add host:3.5 ... usb_del host:3.5 Before the patch 'usb_del' did not support 'host:' notation. ---- Syntax for specifying auto connect filters has been improved. Old syntax was host:bus.dev host:pid:vid New syntax is host:auto:bus.dev[:pid:vid] In both the cases any attribute can be set to "*". New syntax is more flexible and lets you do things like host:3.*:5533:* /* grab any device on bus 3 with vendor id 5533 */ It's now possible to remove auto filters. For example: usb_del host:auto:3.*:5533:* Active filters are printed after all host devices in 'info usb' output. Which now looks like this: Device 1.1, speed 480 Mb/s Hub: USB device 1d6b:0002, EHCI Host Controller Device 1.4, speed 480 Mb/s Class 00: USB device 1058:0704, External HDD Auto filters: Device 3.* ID *:* Signed-off-by: Max Krasnyansky <maxk@kernel.org> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5205 c046a42c-6fe2-441c-8c8c-71466251a162
2008-09-14husb: Make control transactions asynchronous (Max Krasnyansky)aliguori
USB is 99.8% async now :). 0.2% is the three control requests that we need to execute synchronously. We could off-load that to a thread or something but it's not worth the pain since those requests are performed only during device initialization (ie when device is connected to the VM). The change is a bit bigger than I wanted due to the fact that generic handle_packet()/handle_control() interface was not designed for async transactions. So I ended up adding custom handle_packet() code to usb-linux. We can make that generic if/when some other component needs it.

2008-09-11uhci: Change default transaction lifetime to 32 frames (Max Krasnyansky)aliguori
Transaction lifetime was originally set to 10 frames. That was an arbitrary number I picked without much thinking :). I'm changing that to 32 frames because things like interrupt transfers and such are scheduled at that rate. It seems like 1/32 is accepted as lowest supported rate. OHCI, for example, defines exactly 32 interrupt heads. While testing USB webcam under XP I noticed that interrupt transactions were being canceled and then resubmitted on a regular basis, which works but is a waste of CPU cycles. This change fixes that. All other devices I have are not affected.
